This study deals with the delineation and evaluation of spatial variations in the water quality in Multan, Khanewal, Lodhran, Vehari, Pakpattan and Sahiwal district of Southern Punjab, Pakistan. The three major indicators such as EC, SAR and RSC parameters were used and appraisal for irrigation to check groundwater quality via GIS, GS+ software and statistical analysis. The groundwater samples were evaluated for its applicability in irrigation and for mapping consequence. The parameters analyzed were compared with Standards that were adopted by WAPDA, PID and PCRWR. Kriging interpolation maps were delineated with three zone layers such as good (weight = 3), marginal (weight = 2) and bad (weight = 1). It was concluded that the areas under marginal and hazardous groundwater quality with low weights were significantly increased from 2 to 10% and 7 to 40% in pre-and post-monsoon respectively due to analyzed parameters. Hazardous effects were observed more during post monsoon than pre-monsoon season. Most of the area (> 35%) contaminated was due to EC parameters. Most of the study area (tehsil Kabirwala) was observed with low quality against all discussed quality parameters in both season. The groundwater quality parameter weightage decreases from northeast to southwest of study region. Low weightage zones were observed in lower part of the area. It is recommended that in high vulnerability area artificial well recovery, auriferous storage and rain harvesting techniques should be adopted specially in lower part to reduce salinity of water. The policy maker should make policies about regulation of water resources with good quality for best utilization of water for agricultural and industrial use.

A 12-year-old girl presented to our hospital with a history of repeated episodes of oozing of blood from different parts of the body like eyes, ear lobules, nose & navel. She also had history of episodes of hematemesis and haematuria. During examination, bleeding disappeared as soon as it was mopped leaving behind no sign of trauma. Most of these bleeding episodes occurred after stress. Her laboratory evaluation showed; bleeding time, clotting time and prothrombin time were normal. On the basis of clinical presentation and normal investigation, she was diagnosed as a case of hematohidrosis. We treated her with non-specific beta-blocker (propranolol). In spite of the rarity of hematohidrosis, it should be considered as a differential diagnosis of bleeding episodes in patients with normal physical and laboratory investi...

Orthogonal Frequency Division Multiplexing (OFDM) is one of the most vital innovations for UWA communications, having improved data rates and the ability to transform fading channels into flat fading. Moreover, OFDM is more robust on Inter-Symbol and Inter-Carrier Interferences (ISI and ICI respectively). However, OFDM technology suffers from a high Peak to Average Power Ratio (PAPR), resulting in nonlinear distortions and higher Bit Error Rates (BERs). Saving power of battery deployed modems is an important necessity for sustainable underwater communications. This paper studies PAPR in UWA OFDM communications, employing Selective Mapping (SLM) as a tool to mitigate PAPR. The proposed SLM with the oversampling factor method proves to be less complex and more efficient. Simulation ...

The boom in machine learning and intelligent systems provides new perspectives and methods to solve many research problems in Underwater Acoustic (UWA) Orthogonal Frequency Divisional Multiplexing (OFDM) communication. Partial transmit sequence is a tremendous technique for the mitigation of high Peak-to-Average Power Ratio (PAPR) in OFDM communication systems, but finding the optimum phase factors has still a few problems. In this paper, a Partial Transmit Sequence (PTS) based on an Intelligent Detoxification Function of Liver Algorithm-Partial Transmit Sequence (IDFLA-PTS) is proposed for the mitigation of PAPR in the UWA OFDM communication systems. This algorithm reduces the PAPR and the complexity of the proposed UWA OFDM model. The IDFLA-PTS is also compared with the Genetic Algorithm-Partial Transmit Sequence (GA-PTS). Besides this, the Bit Error Rate (BER) performance...

For more development of the MSR reactor, the core system inside the tube is proposed by naturally circulating molten fuel salt. The nonlinear kinetic equations form a linearized function and are obtained in state-space form. Reactivity feedback and delayed neutrons are extremely important for reactor control. In this paper, a thermal-hydraulic system for the commercial computation dynamic model is proposed. Currently, there is no commercial software to simulate the natural circulation flow. The proposed method can be easily employed to detect faults and can provide a feasible overall system performance. Keywords-molten salt reactor; thermal-hydraulic; state-space equation; delayed neutron precursor

The intelligent networks have left their beneficial impact in underwater acoustic (UWA) orthogonal frequency divisional multiplexing (OFDM) communication system. In the UWA communication network the OFDM technology is employed to get a reliable and robust communication. For obtaining better performance of bit error rate (BER) and significant gain in the system, the deep learning auto-encoders are utilized in deep neural networks (DNN). Considering several benefits of auto-encoders in the OFDM system it goes through high peak to average power ratio (PAPR) that makes power amplifier (PA) operating in nonlinear region. So, to maintain the operation of power amplifier working in linear region, this paper proposes a deep learning based PAPR mitigation method termed as T-AE, PAPR method. Firstly, the PAPR is reduc...

As we know there are many software modules that are complex like airline monitoring systems, multi-variable differential equations, AutoCAD 3D drawing, and HD graphics video games that require immense computations that a single processor could not perform. The solution to this problem is to utilize the ubiquitous commodity of modern world – The Multi-Core Processors. A major hurdle in utilizing this commodity is the overhead needed at the developer end to convert a single threaded application into a multithreaded application. This paper intends to find a comprehensive model that could be used to overcome this hurdle by introduc...

The fluid at infinity is assumed to be flowing with a constant free-stream velocity. By using the appropriate transformations for the stream function, the basic governing equations are reduced to a single equation. This equation is solved analytically subject to the relevant boundary conditions by homotopy analysis method. The present analytic solution is uniformly valid for all time. Finally, the results are discussed through graphs.

Since centuries, yield increasing efforts for the cotton crop by conventional breeding approaches have caused an extensive erosion of natural genetic variability. Mutation based improvement strategies provide an effective way of creating new allelic variations. Targeting Induced Local Lesions IN Genomes (TILLING) provides a mutation based reverse genetic strategy to create and evaluate induced genetic variability at DNA level. Here, we report development and testing of TILLING populations of allotetraploid cotton (G. hirsutum) for functional genomic studies and mutation based enrichment of cotton genetic resources. Seed of two cotton cultivars "PB-899 and PB-900" were mutagenized with 0.3 and 0.2% (v/v) ethyl methanesulfonate, respectively. The phenotyping of M1 and M2 populations presented numerous mutants regarding the ...

Then the main focus of this research work is to find the final optimum score based on the previous software metrics used. Then we apply PSO for checking the optimized value based on the results obtained by the Fmeasure(FM), Odd ratio(OR) and Power(PO). We have applied random particle so that fixed biasness is removed through this algorithm. The algorithm used in our approach is shown below. The results are convincing and uniform in different iteration.

The properties used are class, object, inheritance and dynamic behavior. The data modularity considered for this work is 1-10 and 11-20. First the data is arranged in the group and then it is tested based on chi-square test. Then we have calculated F-measure (FM), Power (PO) and Odd Ratio (OR) and find the parametric quality of software metrics. Then we have applied random particle swarm optimization for testing the optimized value and the obtained results found are improved.

Empirical evidence suggests that the 'bank lending channel' is at work at the aggregate level. Loans, deposits and government securities all reduce after a shock to the monetary policy. When we examine bank heterogeneity in terms of size, liquidity and capitalization, the results are mixed. Size is found to be a relevant characteristic. Capitalization, measured by excess capital, is also somewhat effective. Thus, small sized and capital constrained banks respond more to monetary policy signals. Liquidity and the traditional measure of capital, on the other hand, are found to be weaker characteristics. Moreover, the results suggest that the market for loans has a stationary size distribution (no monopolistic tendencies) in Pakistan.

The majority of cristacarpin-treated cells responded to conventional SA-β-gal stains; showed characteristic p21(waf1) upregulation along with enlarged and flattened morphology; and increased volume, granularity, and formation of heterochromatin foci-all of these features are the hallmarks of senescence.

The formation of protein adducts produce structural modifications which generate neo-antigens and induce auto-antibodies. Enhanced oxidative stress and accumulation of HNE-modified proteins are associated with systemic lupus erythematosus (SLE) and other autoimmune diseases. This study has probed the role of lipid peroxidation derived aldehydes in SLE. We report the structural perturbations in human serum albumin (HSA) upon modification with HNE and the consequential enhanced immunogenicity. The induced antibodies were found to be highly specific for the immunogen and exhibited cross-reactivity with HNE-modified epitopes on proteins, amino acids and nucleic acid. The experimentally induced anti-HNE-HSA antibodies appreciably recognized HNE modified epitopes on the HSA obtained from SLE patients. These antibodies, therefore, from a good immunochemical probe to detect such damages in lupus patients. Possible role of anti-HNE-HSA antibodies as a marker for detection/progression of SLE has been discussed.

These antibodies, therefore, from a good immunochemical probe to detect such damages in lupus patients. Possible role of anti-HNE-HSA antibodies as a marker for detection/progression of SLE has been discussed.
